Agraylea CURTIS

Agraylea CURTIS 1834, 217; type species: Agraylea sexmaculata CURTIS 1834 (selected by WESTWOOD 1840, 51).

The genus Agraylea contains only 9 extant species, of which 3 species are West Palearctic, 2 Nearctic, 1 East Palearctic, 2 East–West Palearctic, and 1 Nearctic–West Palearctic (MORSE 2015).

According to MARSHALL (1979), male genitalia of Agraylea generally have a long ventral process on segment VII; segment IX usually has a deep dorso-anal indentation; tergite X is reduced to a short membranous lobe; the inferior appendages are well developed with posterior ends never concave; the subgenital plate tapers posteriorly without any lateral projections but with a median ventral projection in ventral view; and the aedeagus is relatively short and stout with distinct proximal and distal halves and spiral titillator (diagnosis modified from MARSHALL 1979).
